Solvent Compatibility

Updated February 19, 2018 17:52

Resistance to solvents measures deformation after soaking cured resin in the solvent. Learn more about resin solvent compatibility.

Following extensive testing by our materials team, this chart shows observed solvent compatibility with Formlabs resin. Resistance to solvents is measured by observing, measuring and weighing cured resin cubes - originally measuring 1x1x1 cm - before and after soaking in the solvent for 24 hours.

USING ISOPROPYL ALCOHOL

While we do recommend soaking parts in IPA, make sure not to leave your part in the rinse basket for longer than the recommended wash time, because the cured resin is not resistant to IPA. For prints with thin walls, we recommended leaving the part in IPA for even less time.
